Le lumanai ofa'aogaina eletise eletise
Electro optic modulators o loʻo i ai se sao tutotonu i faiga faʻaonaponei optoelectronic, o loʻo faia se sao taua i le tele o vaega mai fesoʻotaʻiga i le quantum computing e ala i le faʻatonutonuina o meatotino o le malamalama. O lenei pepa o loʻo faʻatalanoaina le tulaga o loʻo iai nei, faʻamatalaga lata mai ma le lumanaʻi atinaʻe o tekinolosi faʻaogaina eletise eletise
Ata 1: Fa'atusatusaga fa'atinoga o 'ese'esefa'a fa'aogaina opitikatekinolosi, e aofia ai ata manifinifi lithium niobate (TFLN), III-V eletise absorption modulators (EAM), silicon-based ma polymer modulators e tusa ai ma le faʻaogaina o le gau, bandwidth, eletise faʻaaogaina, tele, ma le gaosiga gafatia.
Fa'ata'ita'iga fa'aogaina eletise eletise fa'avae fa'a-silikoni ma o latou tapula'a
Silicon-based photoelectric modulators malamalama ua avea ma faʻavae o faiga faʻafesoʻotaʻi mo le tele o tausaga. Faʻavae i luga o le plasma dispersion effect, o ia masini ua faia le alualu i luma mataʻina i le 25 tausaga talu ai, faʻateleina le faʻaliliuina o faʻamaumauga i le tolu poloaiga o le tele. O fa'aonaponei fa'aonaponei fa'avae e mafai ona ausia le 4-level pulse amplitude modulation (PAM4) e o'o atu i le 224 Gb/s, ma e sili atu i le 300 Gb/s ma le PAM8 modulation.
Ae ui i lea, o faʻaogaina faʻapipiʻi faʻapipiʻi e feagai ma tapulaʻa faʻavae e afua mai i meafaitino. Pe a manaʻomia e le telefoni feaveaʻi fua faatatau o le sili atu i le 200+ Gbaud, o le bandwidth o nei masini e faigata ona faʻafetaui le manaʻoga. O lenei tapula'a e afua mai i mea totino o le silikoni - o le paleni o le aloese mai le tele o le leiloa o le malamalama a'o fa'atumauina le lava o le amio e tupu ai fefa'ataua'iga le maalofia.
Tekinolosi modulator ua tula'i mai ma meafaitino
O tapula'a o fa'aoga fa'aoga fa'a-silikoni masani ua fa'aoso su'esu'ega i isi meafaitino ma tekonolosi tu'ufa'atasia. O ata manifinifi lithium niobate ua avea ma se tasi o tulaga sili ona folafola mo se augatupulaga fou o modulators.Ata manifinifi lithium niobate electro-optic modulatorsmautofi uiga sili ona lelei o le tele o le lithium niobate, e aofia ai: faʻamalama manino lautele, tele eletise-optic coefficient (r33 = 31 pm / V) laina laina Kerrs aafiaga e mafai ona galue i le tele o galu umi.
O le alualu i luma lata mai i ata manifinifi lithium niobate tekinolosi ua maua mai ai ni taunuuga ofoofogia, e aofia ai se modulator o loʻo galue i le 260 Gbaud faʻatasi ai ma fuainumera faʻamaumauga o le 1.96 Tb / s i le alalaupapa. O le faʻavae e iai tulaga faʻapitoa e pei ole CMOS-compatible drive voltage ma 3-dB bandwidth o 100 GHz.
Fa'aoga fa'atekonolosi ua tula'i mai
O le atinaʻeina o masini eletise eletise e fesoʻotaʻi vavalalata ma faʻaoga fou i le tele o matata. I le fanua o le atamai faʻapitoa ma nofoaga autu o faʻamaumauga,maualuga-saosaoa modulatorse taua mo le isi augatupulaga o fesoʻotaʻiga, ma AI komepiuta talosaga o loʻo faʻaosoina le manaʻoga mo 800G ma 1.6T transceivers pluggable. O lo'o fa'aogaina fo'i le tekonolosi fa'aogaina i: fa'asologa o fa'amatalaga fa'akomepiuta fa'akomepiuta neuromorphic Fa'asologa o le galu fa'aauau (FMCW) lidar microwave photon technology
Aemaise lava, ata manifinifi lithium niobate electro-optic modulators e faʻaalia ai le malosi i masini faʻapipiʻi faʻapipiʻi faʻapipiʻi, e maua ai le faʻaogaina vave o le mana e faʻavaveina ai le aʻoaʻoina o masini ma faʻaoga atamai. O ia modulators e mafai foi ona galue i le maualalo o le vevela ma e talafeagai mo fesoʻotaʻiga quantum-classical i laina superconducting.
O le atinaʻeina o isi augatupulaga eletise eletise e feagai ma ni luʻitau tetele: O tau o gaosiga ma fua: masini faʻapipiʻi lithium niobate modulators o loʻo faʻatapulaʻa nei i le gaosiga o le wafer 150 mm, e mafua ai le maualuga o tau. E mana'omia e le alamanuia le fa'alauteleina o le tele o le wafer a'o fa'atumauina le tutusa ma le lelei o ata. Tu'ufa'atasia ma Fa'atasi: Le atina'e manuia omodulators maualuga-faatinogae mana'omia ai le atoatoa o le fa'atulagaina o mea e mafai ai, e aofia ai le galulue fa'atasi a optoelectronics ma fa'aeletoroni chip designers, fa'atau oloa EDA, vaipuna, ma tagata tomai fa'apipi'i. Lavelave le gaosiga: E ui o faiga optoelectronics fa'avae silicon e la'ititi le lavelave nai lo mea fa'aeletonika CMOS, o le ausiaina o fa'atinoga mautu ma fua e mana'omia ai le tomai fa'apitoa ma le fa'atinoina o le gaosiga.
O loʻo faʻauluina e le AI boom ma geopolitical mea, o loʻo maua e le fanua le faʻateleina o tupe teufaafaigaluega mai malo, alamanuia ma vaega tumaoti i le salafa o le lalolagi, fatuina avanoa fou mo le galulue faʻatasi i le va o aʻoga ma alamanuia ma folafola atu e faʻavavevave le faʻafouga.
